How to distinguish between single and double pneumatic valve plate gate

several types of pneumatic valve plate
the gate structure is divided into wedge and parallel type. There are three kinds of pneumatic wedge gate valve structure: a single structure ( Figure) Relatively simple, but the wedge machining accuracy high, clamping, the scraped high incidence, the precision of the double plate structure ( Figure a) Low wedge, the wedge type gate is not easy to die, but more complex structure, flexible door ( Figure b) The advantage of single and double plate, avoid their weaknesses, which is more widely used. Its structure characteristic is surrounded by a circular CaoMen, make appropriate flexibility. Parallel slide pneumatic valve is usually double plate structure ( C) Pneumatic valve, special purpose, such as the large diameter pipe of long distance oil and gas, and the use of pneumatic valve pneumatic valves clean pipeline structure of single ram needs.

able to distinguish between types of pneumatic valves, such as: ZY - , DN pneumatic valve flange shall be the single ram, nominal diameter, sealing surface material for cemented carbide. Will shut down - in Z Is a two-door, DN pneumatic valve, the other parameters constant. From what can be the appearance of the rough, double plate extruding part pneumatic valve seal is larger than single.

the most common single brake pneumatic valve, low prices, mature technology, reliable sealing
